The Research On Huaqiao2Chestnut Fine Characteristics And Cultivation Technology

From1996to2011, the authors carried out on Huaqiao premature chestnut Seedling selection and cultivation technology research. The main results are as follows:(1) breeding: through the primaries, second choice,third choice, demonstration and extension work, breeding fine varieties types of Huaqiao2chestnut comprehensive economic traits was better than the control variety iron head and double harvest chestnut, clonal offspring genetic stability, economic characters, that Huaqiao2chestnut has fruit early maturity, fruit big, strong adaptability, high yield cultivation management easy, good, commodity value higher good traits, in Hunan in hilly mountain has wide development prospects, is a place for new breed of name spy actor types.(2):breeding seedlings in Huaqiao premature chestnut thoroughbred nursery stock breeding process, after many tests, the winter sowing and film covering technology, uses180/kg seeds, and does not cover film by using135/kg seeds, seedlings ofl years to achieve the same growth effect, can save the cost of seed25%at the same time, put forward to breed the best chestnut rootstock seedlings seed size, do not cover the film size tol35/kg is appropriate, the winter sowing and film coverage can be obtained by using180/kg seeds, large area spring sowing in the later February20th, spring sowing without cover of rice straw and film, cover soil thickness of aboutlcm.(3):carried out cultivation techniques of different slope position on the seedling growth test on the effects of different slope position, that can effect the growth of seedling of chestnut seedling transplanting; launched on afforestation survival rate and growth of, think on afforestation survival rate had no effect, but have a certain influence on growth; carried out using when receive high tree branches of current year as scions on chestnut growth and the results of in vitro studies, think on chestnut growth and results in no effect.(4) pest control:in chestnut orchard production management, the moth luring lamp to forecast, put forward an important pest of chestnut fruit damage of overwintering generation and the first generation adults of the best control time in late April and mid June, the best medicine to deltamethrin and kill bug to Granville, serious harm on the peach borer chestnut orchard7early larvae of centralized control once.(5) the input and output: on Chestnut Orchard of input and output benefit analysis, put forward Chinese chestnut orchard standardization production management and benefit forecast and orchard advocate garden mode, namely farmer voluntarily to garden planting started, and gradually formed the scale.
